Re: [flexcoders] Keep combobox open to allow multiselect
I am still not clear on how this can be done. I must use a combobox (this is
a must-have for me). This is what I attempted... can you please give some
pointers based on my code below?
?xml version=1.0 encoding=utf-8?
mx:ComboBox xmlns:mx=http://www.adobe.com/2006/mxml; change=close()
mx:Script
![CDATA[
override public function close(trigger:Event = null):void {
//Do nothing
}
]]
/mx:Script
mx:dropdownFactory
mx:Component
mx:List
mx:itemRenderer
mx:Component
mx:CheckBox selectedField=isSelected
click=onChange(event);
mx:Script
![CDATA[
private function
onChange(evt:Event):void {
data.isSelected = !data.isSelected;
}
]]
/mx:Script
/mx:CheckBox
/mx:Component
/mx:itemRenderer
/mx:List
/mx:Component
/mx:dropdownFactory
/mx:ComboBox
Thanks

Hi
I have created a combo box with a checkbox renderer on each of its items.
When I select an entry in the combobox, the box closes automatically.
I want to prevent his so that I can multiselect elements in the combobox.
Is there a way to do this? Even if I extend the ComboBox and override its
close method, the combobox still closes (and I realized that there is a
private method in ComboBox.as called destroyDropdown() which gets called
when the collection that the combobox holds changes.
Thanks

Re: [flexcoders] Keep combobox open to allow multiselect
Ram,
The component you are trying to create shouldn´t exetend the combobox
for two reasons, first you would have to override a lot of the
combobox methods and second (and for me the most important) you would
break the common sense of how a combobox should behave for example if
it doesn´t close when you select an item when it closes? What you are
going to show when the user select five items?
If I where you I would make that componente based in the canvas or the
vbox container and give it a diferent look form the combobox (after
all as I said the feel is alredy diferent), you could use a label and
a button (for the closed look) and a list with checkboxes itemEditors
(for the opened look)
